Classification of rotational zero modes in 2D micropolar solids
Dingxin Sun, Yi Chen, Gengkai Hu
Zero modes, which are deformations that cost zero energy, underlie many exotic behaviors in elastic metamaterials. While classical linear Cauchy elasticity explains many of these m…

Unimode material based low-frequency underwater acoustic isolation
Yu Wei, Binghao Zhao, Fen Du +2
Extremal materials are a specific class of Cauchy materials whose elasticity tensor has one or more zero eigenvalues. Each zero eigenvalue corresponds to a soft mode requiring zero…
